A couple of blonde men in a pickup truck drove into a
lumberyard. One of the blonde men walked in the office and
said, "We need some four-by-twos."
The clerk said, "You mean two-by-fours, don't you?"
The man said, "I'll go check," and went back to the truck.
He returned a minute later and said, "Yeah, I meant
two-by-fours."
"All right. How long do you need them?"
The customer paused for a minute and said, "I'd better go
check."
After a while, the customer returned to the office and said,
"A long time. We're gonna build a house."
